MASK FOR ELECTRIiCrLIGHT saunas.

Application filed July 30,

This invention relates to a decorative covering for standard electric light bulbs, and provides a sectional mask including ventilating and fastening means, whereby overheating is prevented and the mask enabled to be applied by one hand while the other hand-is free to be used, if necessary, .to steady the position of the person when the lamps occupy an elevated position.

While the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction maybe resorted .to Within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to .the following description and the drawings hereto attached, in which Figure 1 is an elevational view of a standard electric light bulb, provided with .a decorative covering or mask embodying the invention,

Figure 2 is a View. similar to Figure 1, showing the covering or mask and connectin means in section,

' ,igure 3 is a sectional View on the line 83 of Figure l,

Figure 4 is an end view of the mask the sections in open position, and

Figure 5 is a detail view in section, of .a modification.

Corresponding and like parts are referred to in the following description and designated inthe several views of the drawings by like reference characters.

with The electric lamp shown is of standard formation and comprises the bulb 1 and base 1 and is illustrated to demonstrate the application of the invention.

The covering, or mask, comprises similar sections 2, which conform to the shape of the-bulb 1 so as to completely envelope it and leave a slight space for the circulation of air and to allow for contraction and ex .pansion, without injury to any of the cooperating parts. The sections 2 may be of like or contrasting color, and may be of any construction to produce a decorative effect.

The sections are separable longitudinally, and the meeting edges are ground to insure a close and neat fit which is essential to a 19 6. Serial in. 125,001,

pleasing effect. A .bead .3 is provided upon the outer side of the sections adjacent the upper .end and provides astop for the clamp, whereby the sections are retained in closed position and held in place when applied to the lamp. Longitudinal grooves flare formed upon the inner side of each of the sect-ions and extend through the upper end thereof, and these grooves perform a double office, since the. provide channels for the escape of heate air and seats for the reception of spring fingers 6 forming elements of a.clamp 7 applied to the upper end of the covering or mask.

Thegrooves or channels 4 may be provided in any determinate way best suited to the manufacturer.

The clamp 7 is preferablyo'f spring metal and constructed to encircle the upper margmal portion of the mask, and when closed fastens by a snap action, which admits of application of the device to a lamp by the use of one hand only. The clamp 7 v has a spring tongue 8 at one end, and a projection 9 atthe opposite end, said tongue having an opening or recess to receive the projection 9 when the ends .of the clamps are brought together. Opposite end portions of theclamp are secured to the respective sections of the mask and the construction is such as to admit of the'clamp and the sections being opened, as indicated in F ig ure' 4, so as to receive the lamp, after which the sections 2 are pressed together byclosing the hand, and during this operation the spring tongue 8. rides upon the projection 9 which enters the opening or depression of the spring tongue by a snap action, thereby locking the clamp. In the preferable construction the clamp 7 comprises similar sections which are hingedly' connected, as indicated at '10, one end of the sections being formed with an-opening and the correspond ing end of the companion section terminating in a -hook which is adapted to engage the opening and hingedly connect .the sections, as-will be readily appreciated. .The spring fingers 6 depend from the upperedge of-the clamp '7 and extend along the inner side of the mask and enter thegrooves or channels 4. The flare of the clamp 7 and the outward inclination of the spring fingers 6 is ordinarily sufficient to retain the clamp in place. -owever, springtongues l1".provided at the lower edge of the clamp 7 engage over the bead 3 and further assist I responding and like size, but a trifle larger r 1 when closed about the lamp.

6 is bulged inwardly, as indicated at 12 to yieldably engage thebulb 1, thereby performing the same office as the terminal portions 12, in centering the mask and properly spacing the same upon the bulb 1. The

bulbs of standard incandescent electric lamps are substantially of uniform size and the covering or mask will be provided in corto insure the provision of a slight space between the bulb 1 and the mask when the latter is in position, the mask being centered andyieldably supported by means of the spring portions 12 and 12 of the retaining fingers 6.

It will be readily understood. from the foregoing, takenin connection with the accompanying drawings that the covering, or mask, 7 may with safety, because the device may beheld in one hand, and placed in position about a lamp and the sections brought together by closing the hand, the band automatically fastening by. a snap action,.thereby retaining the mask in position. In the event of the electric lamp being elevated the person applying the mask may, if necessary, use one hand: for safety to gripa suitable support,

such as ladder or projecting part of a struc; ture,

ing the mask in position. The mask may be readily removed by disengaging the spring tongue Sfrom the pro ection 9, when the sections may be pressed apart and the mask detached from the lamp.

The clamp performs the double office of connecting means betweenthesections 2 and locking jmeans for securing .the sections Thus the sections 2 when open, as indicated in Figure i, are maintained in proper relation to admit of the mask being readily applied by one hand which is of vital consequence when the other hand is engaged in steadying the per son. I

Having thus described the invention, I claim:

1. A sectional covering, or mask, for electric lights bulbs and aclamp secured to and be readily placed infposition.

while the other hand is engaged in plac connecting the sections and serving as look ing means therefor to retain the device in place upon the lamp bulb, said clamp auto matically fastening by a snap action when closed.

2A sectional covering, or mask, for electric light bulbs, yieldable means carried by the mask to spaceit from the light bulb and a clamp applied to the mask and comprising similar sections, each attached to a section of the mask and the clamp sections being hingedly connected at one end and adapted to automatically lock at the opposite end by a snap action. r

3. A protector, or mask, for electric light bulbs, the same comprising similar sections, V

a clamp applied to an end portion'of the sections and serving. as connecting means therefor, and having fingers extending along the in'ner'side of the mask and'having portions "or the fingers deflected to yieldably engage the lamp bulb to enter and properly space the mask therefrom.

f. A covering for electric light bulbs, the same comprising complemental sections, a clamp connecting the sections, and serving to retain the covering in place, said clamp having outer spring tongues and inner spring fingers,'tl1e latter having portions defloctcd to yieldably engage the lamp bulb to center and properly space the covering there-"I from. f v

5. A covering for electric light bulbs, comprisin similar sections having longitudinal grooves in the inner side of the upper por-" tion, and a clamp fitted about the upper portion of the sections and having innerfingersentering the said grooves, and having portions of said fingers deflected to yieldably engage the lamp bulb for centering and properly spacingthe covering therefrom.

6. A covering for electric light bulbs, comprising similar sections having an outer bead adjacent its upper end, and a clamp connecting the sections and having inner fingersengaging the inner side of the covering and having spring tongues at the outer sides to engage over the 'said bead.

71A mask for electric light bulbs, the same comprising sections of contrasting color, having theirmeeting edges ground to secure a close fit and having inner longitudinal grooves at the upper end and a clamp secured to the upper end of the sections and adapted to automatically close by a snap ac.- j tion and having inner fingers to engage the said longitudinal grooves andhaving outer spring tongues to engage over a bead formed upon the outer side of the sections.

In testimony whereof I affix my signature.
